Vanes sliding in a rotor are held against the internal surface of an eccentric by springs and hydraulic pressure. The vanes alternately create suction and pressure as the rotor turns. The pump discharges a constant flow of liquid in one direction regardless of the direction of rotation of the driving shaft.

PRINCIPLE OF OPERATION

THREE MOUNTING ARRANGEMENTS TO FIT ANY APPLICATION

Regular models

Stripped modelswith housing

Stripped modelswithout housing

This is an essential feature in any operation where liquids must be pumped in a machine whose driving shaft reverses. BSM Vane Pumps feature a simple, rugged design, a wide range of capacities, and three different mounting arrangements to provide you with the greatest convenience and efficiency in meeting your liquid handling requirements.

MAINTAINS SAME DIRECTION OF DELIVERY WHEN ROTATION OF THE DRIVING SHAFT IS REVERSED

Suction and discharge can be positioned most conveniently for piping because these pumps can be installed in the original position or at any 90 degree or 180 degree position from the original by merely removing bolts and turning housing to desired position on stand.

These pumps simplify installation, particularly where internal discharge and suction ports are not readily incorporated in the machine design, or where outside piping is desirable. A minimum number of easy concentric boring and turning operations are required with readily located tapped holes.

Made for manufacturers who wish to utilize pumps as integral parts of machines with suction and discharge ports incorporated in the machine castings. Provide compact installation and minimum projection from machine surfaces. Furnished with mounting holes and cap screws to simplify installation.

Springs and hydraulic pressure hold the four hardened steel sliding vanes in the rotor against the internal surface of an eccentric and compensate automatically for any wear resulting from contact with the eccentric. Discharge port can be readily transposed in the field.

Typical applications

Replaceable sleeve type and plain bearings are especially adapted for normal pump service to provide long life. Special bearings for unusual or difficult conditions are available.

Compression packing provides an ample safeguard against oil leakage and the entrance of air and is suitable for use with a wide variety of liquids. Special seals for handling corroding liquids are available.

Drive shafts are precision ground hardened steel. Vanes are hardened steel, spring loaded to provide snug fit against the eccentric and to compensate automatically for any wear resulting from contact with the eccentric.

Lubrication of gear cases where reversing cycle is employed; used as a hydraulic brake in mechanical transmissions; general transfer, lubrication, low pressure hydraulic and industrial service.
